Technical Data
Specifications
It is impossible to characterize the listening quality of even the simplest limiter or
compressor based on specifications, because such specifications cannot adequately
describe the crucial dynamic processes that occur under program conditions. Therefore,
the only way to evaluate the sound of an audio processor meaningfully is by
subjective listening tests.
Certain specifications are presented here to assure the engineer that they are reasonable,
to help plan the installation, and make certain comparisons with other
processing equipment.
Performance
Except as noted, specifications apply for measurements from the analog left/right input to
the analog left/right output.
Frequency Response (Bypass Mode; Analog Processing Chain): ±0.2 dB, 50 Hz–9.5
kHz, or as determined by user-settable high-pass and low-pass filters.
Frequency Response (Bypass Mode; Digital Processing Chain): ±0.2 dB, 5 Hz – 15
kHz, or as determined by user-settable low-pass filter.
Noise: Output noise floor will depend upon how much gain the processor is set for (Limit
Drive, AGC Drive, Two-Band Drive, and/or Multiband Drive), gating level, equalization,
noise reduction, etc. The dynamic range of the A/D Converter, which has a specified
overload-to–noise ratio of 110 dB, primarily governs it. The dynamic range of the digital
signal processing is 144 dB.
Total System Distortion (de-emphasized, 100% modulation):
